I just went out and looked at the pwer jack on the front of my 2011
On mine there are two removable black plugs one on each side that
when removed reveal a bolt, but not anykind of access to manually
use the front jack.
As stated above, plug the 7 pin into your truck and that should give
you enough power to run the jack up or down as needed.
In the future when you store your TT you may need to unhood the
battery wire since there are power eaters in the trailer that will
draw down your battery while in storage (ie. clock, carbon monozide
monitor, or you left a light turned on?).
But all that said, on my car trailer the electric tunge jack has a wrench
to manually crank it up or down.
